IMPROVEMENT IN SETTING- GAS-RETORTS.

The Schedule referred to vin these Letters Patent and making part of the same I, THOMAS GURLEY, of Wilmington, State of Delaware, have invented certain Improvements in the Settingof Gas-Retorts, of which the following is a speceatiou.- l

Theiirstlpart of my invention relates to providing clay retorts with protecting tile or shields where the action ofv the flame, or heat strikes with greatest force, tov prevent uneven expansion and contraction, and consequent rapid destruction of the salue.

The second part of p my invention relates to providing adjustable dampeis in the exit-dues ot' retort-settings,.in such a manner that, when the dampersare closed, the heat is confined so as to permit the furnacedoors to be opened to supply fuel or to remove clinkers and the like, without permitting a cold draught ot. air to enter, and, by sudden cooling of the retorts, cause them to crack and give out, as theyare liable todo in ordinary settings.

Figure 1 is a. front elevation of ay setting of one bench.

a a a a are the retorts.

b is the furnace.

'c c are the saddle-tiles.

d d, the lower protecting shield-tiles.

e e, the upper protecting tiles or shields.

At o o are the exit-fines.

g g are the ordinary fixed dam'pers.v

h h, the adjustable dampers and mechanism for operating them, consisting of shaft m, bell-cranksp p,

connecting-rods or levers i e' and k k, pendant I, and

handle n. A

Figure 2 is a side elevation of a bench, showing the position of the hydraulic main j, and the different parts of the damper mechanism before mentioned.

Figure 3 is a perspective view of the protectingtile e, shown at ee in iig. 1.

In ordinary settings of retorts, those parts of the retorts shown herein as protected by tile l d and c e are exposed tothe full action of the heat from furnace b, and more especially at the middle parts of the retorts.

This causes unequal expansion and contraction, which soon causes the retorts to crack and give way, causing frequent expensive renewals.

By the use of the protectng-tiles or shields at such parts of the retorts as are most exposed to the heat, the retorts will last from seventy-tive to one hundred per cent. longer.

The protecting-tiles are so arranged as tobe replaced withV little trouble,l without resetting the retorts or other disturbance ofthe settings.

In ordinary settings, also, the xed damper atg g allows a strong draught of cold air to enter the furnace when the doors are opened for the purpose of clinliing, the time foru-'hich, and until the fresh fuel is again ignited, is about .half an hour. This s uddenly cools the retortsand settings, and causes them to crack and give way.

It also cools oi the bench, which lessens the quau tity and injures the quality of the gas, and increases the'quantity of'fuel necessary to distil an equal volume of gas, all of which is avoided by the use of the adjustable dampers h h, operated, as will be readily understood, by `simplymoving up or down the handle n of rod l, which acts through the cranks p p and levers k k and i i, and shaft in., to close or open the exit-fines o o.

I do not confine myself to this particular mechanical arrangement, but any other-equally efficient, for

closingl and opening the exit-fines. l

C laims.

I claim as my inventionf 1. The renewable protecting-tiles or shields d d and e e, in clay retort-settings, substantially as and for the purposes hereinhefore set forth.

2. 'lhe 'adjustable or independent damper h h, placed in the exit-flue of retort-settings or benches,

for the purposes described and set forth.
